Small Oud Bruin

Three weeks ago I racked my first sour beer into a barrel to age for a few months. The yeast cake I racked from contained precious microbes from the bottom of a Jolly Pumpkin Bam Biere that I didn't want to waste. I held on to the cake until I could figure out what to do with it. Then opportunity knocked.

My friend in brew, Mike, was planning to make a high gravity stout to celebrate the upcoming holiday season. He offered me the second runnings off his mash. It was an offer I couldn't refuse. Thanks buddy!

The boil was super uneventful. I used a small FWH addition of Columbus to bitter it up because that's what I had in the freezer. Plus, it's Columbus day! How can you pass up that coincidence! Some Irish moss at 15 min. was the only other boil addition. Chilled down to 85F with the wort chiller then further to 71F in an ice bath. Then I spent a few minutes 'rousing the beast' to get the yeast cake to become a homogeneous solution again. Then, instead of pitching yeast, I pitched the wort on top of this recently roused yeast and bug farm.

Despite having not tasted the Bam Biere clone yet, I'm excited at the possibility of having a yeast cake with a history and a lineage. Bam Biere clone begat Sour Stout begat... whatever's next. Once this has spent enough time on the cake (I really have to name this thing) I'm thinking of racking onto a pound or two of sour cherries. Fingers crossed on this not tasting nasty.

10/31/15 - Halloween update. This beer took about 2-3 days before there was any visible fermentation activity. I'm blaming the WLP 550 since I think it's a slow starter. Gravity is down to 1.008. Brown in color, a little bit malty, and a little bit tart already. Has the aroma of a sour and a little of the bite but not much. Will wait and see how this develops before any fruit ageing occurs.

2/1/15 - Kegged my first sour today. Refreshingly tart for a dark ale. Light gravity and light sourness make it kind of a thirst quencher.
